JOHN R. DEIHM, OF POTTSVILLE, PENNSYLVANIA.

SPRING BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 320,765, dated June 23, 1885.

Application iiled December 5, 1884.

To a/ZZ whom, it may concern:

Be it known that I, J onN It. DEIHM, ot Pottsville, in the county of Schuylkill and State of Pennsylvania, have invented a new and Improved Spring Bed-Bottom, of which the following is a full, clear, an d exact description.

This invention relates to the construction of the bed-bottom itself, .and to means whereby the bottom may be tightened up, the same bcing adapted to be applied to the frame of the bed, thus avoiding the use of aseparate frame for holding the bedbottom.

Reference is t0 loe had Ito the accompanying drawings, forming part of this spccitication, in which similar letters of reference indicate corresponding parts in both the Iigures.

Figure l is a broken plan View of my invcntion applied to an ordinary bedstead; and Fig. 2 is a sectional elevation of the same, taken on the line x x of Fig. l.

The bedstead A, consisting of the side pieces, a ci, foot-board b, and head-board c, may be of the usual or of any approved construction. The spring-bottom B is composed of the coiled Wires d and linleplates e, to which the wires are fastened, the plates c each being formed with four holes, c', for that purpose. The plates e are secured together by the short wire links f, that are fastened in the central slots, j, made in the plates e, as shown clearly in Fig. 1, thus permitting the plates e to have slight lateral movement without strain upon the coiled wires d. Formed with or attached to the coiled wires d are the straightwires d', by which the end coiled wires, d, in the bottom are fastened to the stretching-rollers O, by which the bottom may be tightened up. These rollers O are by preference made tubular, and are each formed with the series or holes g, through which the wires d pass. They are each provided at one or both ends (preferably at both) with a ratchet-wheel, h, with which the pawls z', pivoted to the inner surfaces of the side pieces, a, of the bedstead, are adapted to engage, for holding the rollers C from turning back when the bed-bottom is tightened by turning the rollers.

For securing the tubes or rollers C to the (No model.)

side boards, a a, of the bedstcad, I employ the open journal or bearing plates C', so that the tubes C may be put in place in the bedstead and removed without taking down the bedstead. The plates C' are each formed with a bearing or journal, j, and the edge of theplates is cut away down to the bearing j, as shown at j', forming an entrance to the bearing j of suiiicient size to admit the ends of the tubes O, and by preference the plates O'are recessed, as shown at 7c, to receive and inclose the ratchet-wheels l1.; but this may be omitted it the ratchcts hare made of the same or less diameter as the tubes O, and the plates O' are secured to the inner surfaces of the side pieces, a, by screws Z, so that my invention may be applied to any bedstead. lll/hen the tubes O are put into the bearings O, and the wire bottom attached to them by the straight wires d', the bottom may be tightened up by simply turn ing one or both of the tubes C by means of a wrench, or otherwise, and in case the bottom becomes slack by use it may be easily tightened, and the bottom maybe made very tight or somewhat slack, as desired by the user; and by means of open bearing or journals, that hold the rollers O, no diicultywill be experi enced in taking down or setting up the bed, and in addition to these advantages the bedis practical,cl1eap, durable, and very convenient, and may be applied to any bed without the use ot aseparate frame.

Without the straight wires (Z the bott-om could not well be tightened up, as above set forth 5 hence this forms an important part of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

The bottom B, composed of slotted plates e, coiled and straight wires d d', and connecting-links f, in combination with the rollers O, for tightening up the bottom, substantially as described.
